SAW-SET.

SPECIFICATION forming part of Letters Patent No. 617,612, dated January10, 1899.

Application filed July 19, 1898- Scrial No. 686,337- (No model.)

To all whom it may concern.-

Be it known that 1, JOHN H. STUKE, a citizen of the United States,residing atBeardstown, in the county of Cass and State of Illinois, haveinvented new and useful Improvements in Saw-Sets, of which the followingis a specification.

My invention relates to saw-sets; and its obj ect is to provide animproved construction of the same which shall possess superioradvantages with respect to efficiency in use.

The ordinary or usual devices for setting saws are Very defective inthat it is almost impossible to have the tool hold the saw in properposition and every tooth set exactly alike. By my invention such defectsare obviated.

The invention consists in the novel construction and combination, ofparts hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of a set-sawconstructed in accordance with my invention. Fig. 2 is a longitudinalsection of the same.

In the said drawings the reference-numeral 1 designates a metal blockcomprising the two arms 2, with a space or slot therebetweem'one of saidarms being beveled, as at 3, on its inner side. These arms are connectedtogether at the upper ends by the horizontal portion 1, formed with anaperture 0r hole 5, for a purpose hereinafter described; also, formed inone of said arms is an inclined hole or passage 6 for the passage of aplunger, which will also be hereinafter described,which hole intersectsthe slot between said arms.

The numeral 7 designates two lugs, and 8 an outwardly-extending arm,forming a handhold.

Located in the slot or recess between the arms 2 is a wedge-plate 9,provided with a shank 10 at its upper end, to which is pivoted a cam 12,by turning which the wedge-plate can be elevated and held in suchposition. Located in the inclined passage 6 is a plunger 13, providedwith a head 14 and formed with a slot 15, through which passes a pin16,which holds the plunger in place. A coiled spring 17 encircles saidplunger. Pivoted to the to which the lever 18 is pivoted is formed witha recess, in which is located a plate 21, pivotally connected therewithand provided with a spring 23. Bearing against this plate 21 is aset-screw 24. for throwing it forward, so as to change its inclination.The said plate 21 is beveled on its inner side, as seen at 25.

The operation is as follows: The saw is inserted in the block 1 betweenthe straight or vertical side of one of the arms and the correspondingside of the wedge, and when in proper position for setting the saidwedge is drawn upward by turning the cam 12, which will cause the wedgeto securely clamp the saw between it and the block. The beveled plate 21is now adjusted at the proper angle by means of the set-screw, and thelever 18 is depressed by grasping it and the arm 8 and forcing saidlever outward, when the lug on the lever will engage with the head ofthe plunger, forcing it forward and causing the end thereof to force thesaw-tooth against plate 21, thus setting the same, so that all the teethwill be set exactly alike.

Having thus fully described my invention, what I claim is- 1. In asaw-set, the combination with the block having a slot therein, and themovable wedge located in said slot, of the plunger, the lever, thespring-actuated beveled plate and the set-screw for adjusting the same,substantially as described.

2. In a saw-set, the combination with the block formed with a slot, thewedge located in said slot, the shank of said wedge passing through saidblock, and the pivoted cam, of the plunger, the lever for operating thesame, the spring-actuated beveled plate, and the set-screw,substantially as described.

3. In a saw-set, the combination with the block, comprising the twoconnected arms with a space therebetween, the wedge located in saidspace formed with a hole or aperture,

the shank passing through said block and proate vided With a pivotedca1n,tl1e headed plunger, the coiled spring and the pivoted leverprovided with a shoulder engaging with said plunger, of the pivotedspring-actuated beveled plate and the set-screw for adjusting the same,substantially as described.

I11 testimony whereof I have hereunto set my hand in presence of twosubscribing Witnesses.

JOHN H. STU KE.
